A 21-year-old man was shot in the back Thursday night on the 5200 block of Clayton Drive in Baton Rouge, police said.

Baton Rouge Police Department spokesman Cpl. L’Jean Mckneely said that the man was walking home from grocery shopping with another person at about 9 p.m. when a male suspect walked up behind them and shot the man multiple times.

The man’s injuries were life-threatening, but Mckneely said Friday afternoon he is in stable condition.

Mckneely said the injured man and the suspect might have known each other.

“We believe, though we’re not 100 percent sure, that it’s stemming from some type of issue or altercation in the neighborhood,” Mckneely said.
